摘要
电网中运行的支柱瓷绝缘子,长期服役后有可能发生失效,导致恶性事故的发生。如何有效检测出导致失效的裂纹具有重要意义。文章介绍了使用超声爬波法对该类瓷瓶进行检测的方法,该方法在现场应用中取得了良好的效果。
The post insulators operating in power grid may have failures after long term service and caused severe accident. It is of great significance to effectively detect the cracks that caused failure. This paper introduces the methodology using ultrasonic creep waves to inspect such insulators, and such methodology has achieved good result in field application.
